The term ‘membrane bioreactor’ (MBR) is usually used to define wastewater treatment processes where a perm-selective membrane e.g. microfiltration or ultrafiltration is joined with a biological process – a postponed growth bioreactor.
Membrane Bioreactor (MBR) systems proposal some effective and economic compensations equated to conventional wastewater treatment plants. By incorporating GE’s membrane technology, MBR systems eliminate the need for secondary clarifiers and tertiary treatment. This allows for increased performance with a smaller footprint.
MBRs differ from ‘polishing’ methods where the membrane is employed as a discrete tertiary treatment step with no return of the active biomass to the biological process.
